This invention relates to journal boxes and comprises certain improvements in the construction and mounting of the journal box lid and the spring provided for holding the *5 lid in open orclosed position.

A particular objectof the invention is to provide improved means for releasably holding-in place the hinge pintle connecting the lid to the journal box, said means permitting 1 the pintle to be readily freed for removal by a simple movement of the lid after the spring vpressure exerted on the lid has been released. .Another object is to provide a lid having a continuous marginal flange fitting over the nal box to prevent entrance of dirt and dust between the lid and the body portion ofthe box.

Another object is to provide a rugged and Veconomical lid construction in which the dust 20 excluding flange, the pintle receiving sleeves and. the spring supporting and retaining means are all cast integral with the body por,- tion of the lid.

. A further object is to provide a generally 1""25 improved and simplified lid and springy as in which the spring is held to the lid sembly ith the body portion by parts cast integral w `of the lid.

Other objects and advantages of the invendily understood from the following detailed description and accompanying drawlings7 whereinvFigure 1 is a perspective view of a journal box equipped with al lid and spring assemccordance with this invention. In this view the lidv is shown in closed position.

lid showing the manner in which the bore of one of the pintle receiving slots is partially Vclosed at its outer end.

Referring more particularly to the drawings 11 designates a. journal box providedr with the usual mouth opening 12 and pintle lug 13. The lid 111 is cast with a continuous inwardly projecting marginal flange 15 adapted to lit over the wall 16 surrounding the mouth opening 12 in order to prevent.0 the entrance of dust 'or dirt. A U-shaped rib 17 is formed to project inwardlyv from the lid infspaced relation to the flange-15 and serves as anoil deflector, as is well known in this art. Pintle sleeves 18 and 18 aref cast'integral with the body of the lid and the upperportion of the flange 15 to receive the ends of the hinge pintle 19passing loosely through the lug' 13. The lug 13 is provided with the usual-angularly related fiati? cam kfaces 13a and 13b adapted to co-operate roller 2O to hold the lid in eitherk open or closed position. The roller carrying spring consists of vtwo coils 21 and-22 connected by an intermediate U- shaped portion 23 which is formed as an integral continuation of the inner terminal convolutions of the coils and carries the rolllutions of the coils ed downwardly along?.- the outer face of the'lid'to provide a pair allel side arms l24@ having their lower ends received in vertical sockets 25 cast integral with the outer face of the lid.' The coils 21 and'22 bear against the inner sur-7 face of a transversely curved fulcrum or retaining member 26 which extends across the upper central portion of the lid and has its ends integrally joined thereto by means of the parallel sie@ Wang or Webs 27. The 10W-f90 er portions of these webs 27 form the outer sidewalls of the sockets 25 while the upper portions of said websy are merged with the inner ends of the pintle sleevesl 18 and 18. The outer face of the lid may also be formed 95 with` a U-shaped strengtheningrib 27 presenting a horizontal-portion 28 positioned adjacent the lower edge of the lid and vertical portions 29 extending upwardly in spaced relation to the side edges of the lid' 65 with' reference to the sleeve 18 is and merging with outer end portions of the pintle sleeves. .When the lid is in the closed portion shown in Figure the engagement obtaining between the roller 20- and the cam 5 face 13a of the lug 13 causes the parallel arms 24 of the spring to exert pressure against the central portion of the cover to hold the cover firmly againstthe contacting faces of the journal box. When thelid isA raised to the open position shown in Figure 6 the roller 20 rides over the cam face 13a of the lug 13 and onto the cam face 13b so that in this position of the roller with reference to the lug 13 the spring becomes effective to retain the lid in its open position.

When the parts are assembled as shown in Figures 1 and -2 the hinge pintle is held in place by a particular formation of the pintle sleeves 18 and 18 which will now be described. vAs shown ,to advantage in F igures 4 to 6 inclusive each sleeve is provided With'a pintle receiving bore 18a which is generally elliptical or oval in vcross section being formed with the axis A longer than the axis B. These bores extend through to the inner surfaces of the'p'intle sleeves but are partially blocked at Atheir outerends. ln thecase of the sleeve 18 the outer end of the bore is partially blocked'bya continuous pintle engagingfiange or ledgel30 leaving a relatively small opening 31 for the insertion of a tool `for the purpose of removing the pintle, as hereinafter described.' The outer end of the bore formed in the sleeve 18 is partially blocked by a crescent shaped yledgefor flange 32 which leaves a circular *opening 3 3 for vthe insertion ofthepintle. j In applyingthelid a suitable tool is engaged beneath the roller to press same in the direction ofthe spring retainingor fulcrum member' 26 in order to permit the bores 'ofthesleeves 18 to be aligned with the pintle receiving opening of the lug 13. lThe pintle 19 is-then passed vthrough the circular' opening 33 of the sleeve18 so that the kends'of the pintle are seated in thesleeve bores with the central portion of the pintle passing through the lug 13. -The length of the pintle is such that when one end is Vengaged with the flange or ledge 30of the sleeve 18 the other endlies inwardly of the crescent shaped flange or ledgey 32 of the sleeve 18". l Theelliptical or oval shape ofthe sleeve bores f provides sufficient clearance kto permit the sleeves to be moved laterally with reference to the pintle by the pressure" of the spring ,roller 20 when this roller is released to bear against the lug 13. This'lateral movement of fthe sleeves causes the crescent shaped ledge or the pintle to form a stop preventing outward V.movement of the opposite end of the pintle with Areference to the sleeve 18. movement of the opposite end of the pintle prevented of the lid, sockets tion thereto.

lug, a lid provided the webs flange 32 to move opposite the adjacentend of Outward by the continuous flange or ledge 30. When the pintle is to be removed the pressure of the spring roller against the lug 13 is released to permit the sleeves to be shifted to a position bringing the circular opening 33 of 70 the sleeve 18 opposite the adjacent end of the pintle so that the pintle'can be driven outwardly through this opening vby means of a tool insertedthrough the opening 31 of the sleeve 18. j Y y I Another advanta'geof the lid and spring .assembly described in the foregoing is that the spring retaining or fulcrum member 26 extends over-the-upper portion of the coils 21 and 22 a suflicientdistance to hold the 80 spring arms 24 against accidental .escape from the l sockets 25.- l.It w'ill -thuss1be'seen that the lid and spring assembly as described hereinmay be shipped to the pointof use" without any danger of accidental sepa-ration and maybe appliedto the journal box or removed therefrom as a unit.

Having thus described my invention, what Iclaimis: y
